600x600 is a widely used square dimension for product images on e-commerce platforms, profile pictures, and social media preview images. It provides good quality while keeping file sizes small.
Many e-commerce platforms recommend 600x600 as a minimum product image size. Etsy, eBay, and various marketplace platforms use this dimension for product thumbnails in search results.
With ImgTools, upload your image, crop to a 1:1 square if needed, and resize to 600x600. For product photos, ensure the product fills most of the frame with consistent margins.
Save as JPEG at 85% quality for photographs. At 600x600, the file will be 30-60KB.
